Zero-byte .M Objective-C Implementation File

Download a zero-byte .M file, or one of about 1 KB, for QA. Neither file is a real document.

About this Zero-byte .M file

What you get

empty.m is 0 bytes. 1kb.m is 1,024 bytes of filler text. Both use the Objective-C Implementation File name.

How to use it in QA

Attach either file where your product asks for a .M file. Use the empty file for a zero-length check, and the 1 KB file for a small non-empty upload. The download names stay empty.m and 1kb.m.

What is inside the files?

Will an app open them?

Most apps will report an empty or invalid Objective-C Implementation File. That is the point of the fixture.

Is the download safe?

Yes. Neither file has an executable payload.
